Abstract
Abstract A carton constructed of a single folded cardboard blank having hollow wall units along the periphery thereof, means on each of the walls at opposite ends thereof for interlocking adjacent walls together, said locking means being located on the upper wall portions of the hollow wall units and being so arranged as to require opposing ones of hollow wall units to be moved inwardly and subsequently outwardly to effect the interlock between adjacent walls. Moreover, the spacing between the lower ends of the inner and outer walls of each wall unit is slightly less than the width of the respective top wall of the unit, thereby permitting the item stored within the carton to be snugly held in place during shipment.

Total Claims: 4
Claim 1
Independent Claim
224 words
A carton made from a single blank of material comprising: a rectangular base panel; an integral hollow wall unit along the periphery of said base panel at each of the four end edges thereof; each of said hollow wall units comprising spaced inner and outer side walls interconnected by a top wall, the width of each said top wall being greater than the spacing between the respective ones of said inner and outer side walls at the lower portions thereof; glue flaps on said inner walls for securing each of said units to said base panel; locking tongues on each of said top walls at opposite ends thereof for interlocking adjacent units together through interengagement of adjacent tongues, said locking tongues on a first opposing pair of said units being provided with outwardly open locking grooves, and said locking tongues on a second opposing pair of said units being provided with inwardly open locking grooves for respectively engaging with said outwardly open grooves, said grooves each being of a predetermined width, whereby, upon interengagement of said adjacent tongues, each of said inner walls are disposed perpendicularly with respect to said base panel and each of said outer walls are slanted outwardly with respect to said base panel by reason of said relative widths of said top walls and said inner and outer wall spacings.

The carton according to claim 1 further incluDing a wrapper snugly in contact with the outer surfaces of said top walls, said outer side walls and said base panel for causing said outer walls to be disposed perpendicularly with respect to said base panel and said inner walls to be slanted inwardly with respect to said base panel, whereby the product to be supported on said base panel between said opposing hollow wall unit pairs is snugly held in place by said inwardly slanting inner side walls abutting against the end and side walls of said product.
Claim 4
Dependent Claim
48 words
The carton according to claim 1 wherein said opposite ends of each said top wall each lie along a diagonal line extending between said outer side walls and said inner side walls of each said unit, said tongues extending outwardly of said opposite edges of each said unit.
